Problem Description
The current Open WebUI application database allows configuration of the PostgreSQL database pool size and max overflow for the application database. However, similar configuration options are not available for the pgvector database. This limits the ability to manage database connections and tune performance specifically for the pgvector database.
Desired Solution you'd like
Add support for configurable pool size and max overflow for the pgvector database. This would allow users to better manage database connections and potentially improve performance.
